The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 is the decomposing schematic representation of the first embodiment of the present invention, and Fig. 2 is the overall structure schematic diagram of the second embodiment of the present invention; Fig. 1 and Fig. 2 main is not but that the air chamber 7 of the second embodiment is body components with cylinder 4, and in the first embodiment, air chamber 7 is discrete parts with cylinder 4.
Main thought of the present invention is to move by air pressure pushing piston bar, moves grease nipple by the piston rod of motion and blocks a shot to complete installation.
As shown in Figure 1, air chamber 7 is connected with cylinder 4, and air chamber 7 is communicated with cylinder 4.
Cylinder 4 forms hollow, wherein accommodates piston head 6, piston spring 5, piston rod 16, cushion pad 2, and cylinder 4 also is formed with steam vent 3 in the precalculated position, and steam vent 3 can be the bi-directional venting hole, namely forms the through hole that connects cylinder 4.
Cushion pad 2 is fixed on the second end of cylinder 4, and the second end of piston spring 5 is supported on the first side of cushion pad 2; Cushion pad 2 centers are formed with through hole, slidably the second end of support piston bar 16; The first end of piston rod 16 is provided with piston head 6, and piston head 6 is arranged at the first end of cylinder airtightly, and can slide along the inwall of cylinder; The first end of piston rod spring 5 is arranged on the second side of piston head 6.Piston spring 5 arranges around piston rod 16.
The second end of rifle head 1 is formed with the accommodation section 15 of blocking a shot, to place the block of waiting to arrange to grease nipple; The center of running through rifle head 1 is formed with guiding channel, and guiding channel is communicated with cylinder 4 with the accommodation section 15 of blocking a shot, make piston rod 16 to move along guiding channel.The first end of rifle head 1 is connected with the second end of cylinder 4, is preferably to be threaded.
Air chamber 7 preferably arranges air pressure valve 8, to regulate the air pressure size in air chamber 7.
Air chamber 7 is connected with the unidirectional delivery outlet of crossing air valve 10 by conduit 9.The unidirectional input of crossing air valve 10 connects wireway 13, to receive the gas with certain air pressure from the outside.The unidirectional air valve 10 of crossing comprises control lever 10a, and the user can control the unidirectional break-make of crossing air valve 10 by control lever 10a.
Shell 14 is used for surrounding covering air chamber 7.
Corresponding to control lever 10a, be provided with rotationally valve 11 on shell 14 or cylinder 4, valve 11 contacts with control lever 10a, controls the unidirectional break-make of crossing air valve 10 thereby the user can operate control lever 10a by valve 11.
Grip for convenient, also can comprise handle 12.Handle 12 can form the shape of various suitable grippings as required.Handle 12 can be to be combined in as shown in Figure 2 air chamber 7 bottoms, and the unidirectional air valve 10 of crossing is contained in handle 12.Handle 12 also can be arranged on unidirectional air valve 10 bottoms excessively as shown in Figure 1, and this moment, the unidirectional air valve 10 of crossing was not contained in handle 12.
Preferably, wireway 13 is contained in handle 12.
Although in Fig. 1 and Fig. 2, rifle head 1 is discrete parts with cylinder 4, design is to change the different rifle head of accommodation section size for the block of convenient corresponding different size like this.But rifle head 1 also can form as one with cylinder 4 here.
As described in Figure 2, the unidirectional structure of crossing air valve 10 is column cavity, spring, piston, control lever; Spring supporting is on a sidewall of cavity and in a side of other end support piston, another side of piston is connected with control lever, is formed with input hole A, bleeder port B and delivery outlet C on cavity, and the middle part of piston forms the space that is communicated with; When control lever was depressed, spring was compressed, and piston moves to the left side in figure, and the space of connection is communicated with input hole A and delivery outlet C and seals bleeder port B, gas circuit conducting; After the control on control lever removed, spring made the position of piston reset, and gas circuit disconnects.After piston reset, the gas in air chamber 7 can drain into the outside via delivery outlet C, bleeder port B.Need to prove, the unidirectional air valve of crossing of the present invention is not limited to the check valve of structure shown in Fig. 2, as long as can serve the same role, the check valve of other structures also can be used in the present invention.
The below is briefly described the course of work of grease nipple block rifle of the present invention.
When the unidirectional control lever 10a that crosses air valve 10 is depressed when being depressed by valve 11 (or), the gas circuit conducting, gas enters air chamber 7 from source of the gas via wireway 13, the unidirectional input hole of crossing air valve 10, the unidirectional delivery outlet of crossing air valve 10, conduit 9, after reaching certain pressure, pushing piston head 6 moves in cylinder, and the piston rod 16 that is connected with piston head passes cushion pad 2 and moves right also compression piston spring 5.Piston rod 16 enters rifle head 1 and arrives block accommodation section 15 along the guiding channel of rifle head 1, moves the block in block accommodation section 15, completing the block operation.When piston head 6 moved further to the right, air chamber was communicated with steam vent 3, and the gas in air chamber 7 is discharged to the outside by steam vent 3, can not be further compressed and move right to guarantee piston head 6.
After the unidirectional control lever 10a that crosses air valve 10 is released when released (or by valve 11 and), the unidirectional air valve 10 of crossing resets under spring action, and delivery outlet C is communicated with bleeder port B, and the gas in air chamber 7 is discharged to the outside via bleeder port B.Piston head 6 resets under the effect of piston spring 5.
Although illustrated and described the preferred embodiments of the present invention, it is contemplated that, those skilled in the art can design various modifications of the present invention in the spirit and scope of claims.
